Z-Glu(Phe-OEt)-OBzl is a synthetic peptide compound consisting of three amino acids: glutamic acid (Glu), phenylalanine (Phe), and a protected glutamic acid (Z-Glu). The "Z" group is a benzyloxycarbonyl (Z) protecting group, which is commonly used in peptide synthesis to prevent unwanted side reactions. The phenylalanine residue is attached to an ethyl ester (OEt) group, which can be used to facilitate the synthesis process or for specific biological activities. The entire peptide is capped with a benzyl (OBzl) group, which serves as a protecting group for the carboxylic acid terminus. Z-Glu(Phe-OEt)-OBzl is often used in the field of organic chemistry and peptide synthesis for the study of protein structure, function, and drug development.
The CAS Registry Mumber 4210-89-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,1 and 0 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4210-89: (6*4)+(5*2)+(4*1)+(3*0)+(2*8)+(1*9)=63 63 % 10 = 3 So 4210-89-3 is a valid CAS Registry Number.
